How to Improve MPG | 10 Fuel Saving Tips UK

1. Drive Smoothly to Improve MPG

Aggressive driving is one of the biggest causes of poor MPG. Rapid acceleration and harsh braking force your engine to use more fuel than necessary.

Driving smoothly, accelerating gradually and braking gently can quickly improve your fuel efficiency, especially in stop-start traffic where MPG typically drops the most.

2. Maintain a Steady Speed

Frequent changes in speed can negatively impact your MPG. Keeping a consistent speed allows your engine to run more efficiently and use less fuel.

On longer journeys, maintaining a steady pace can noticeably improve MPG, particularly on motorways where constant acceleration can quickly reduce fuel economy.

3. Check Your Tyre Pressure for Better Fuel Efficiency

Incorrect tyre pressure is a common cause of reduced MPG. Under-inflated tyres increase resistance, meaning your car needs more fuel to move.

Keeping your tyres properly inflated helps improve MPG, reduces fuel costs and improves overall vehicle safety.

Keep Your Car Running Efficiently

If you’re unsure when your tyres or vehicle were last checked, a quick inspection can make an immediate difference to your MPG.

4. Remove Unnecessary Weight

Extra weight in your vehicle directly impacts fuel consumption and lowers MPG. Carrying unnecessary items, especially over long periods, means your engine has to work harder.

Clearing out your boot and removing unused roof racks can help improve MPG, particularly on longer journeys.

5. Avoid Short Journeys Where Possible

Short trips are one of the biggest contributors to poor MPG. When your engine is cold, it uses more fuel, and on short journeys, it rarely reaches peak efficiency.

Combining trips or reducing short-distance driving can improve your average MPG over time.

6. Use Air Conditioning Efficiently

Air conditioning can reduce MPG by placing extra load on the engine. While it’s important for comfort, using it only when necessary can help improve fuel efficiency.

At lower speeds, opening windows may be more efficient, while at higher speeds, keeping windows closed helps maintain better MPG by reducing drag.

7. Use Gears Efficiently

Driving in the wrong gear can have a significant impact on MPG. Staying in lower gears for too long increases engine revs and fuel consumption.

Shifting gears at the right time helps improve MPG and keeps your engine running efficiently.

8. Keep Your Car Serviced

A poorly maintained vehicle will almost always return worse MPG. Dirty air filters, worn spark plugs and old engine oil can all reduce fuel efficiency.

Regular servicing helps maintain optimal MPG, ensuring your car runs as efficiently as possible and avoids unnecessary fuel waste.

Improve MPG with Regular Maintenance

Keeping your vehicle in top condition is one of the easiest ways to reduce fuel costs long term.

9. Anticipate Traffic to Reduce Fuel Use

Looking ahead and reacting early helps you avoid unnecessary braking and acceleration, both of which reduce MPG.

By maintaining momentum and driving more predictably, you can improve fuel efficiency and make every tank last longer.
